Canmore’s share of its area codes

Within area code 403, Canmore accounts for only 11 of 781 prefixes (1.4%): the code is dominated by Calgary and spread over 142 rate centres. Within area code 587, Canmore accounts for only 7 of 779 prefixes (0.9%): the code is dominated by Calgary and spread over 137 rate centres. Within area code 825, Canmore accounts for only 7 of 769 prefixes (0.9%): the code is dominated by Calgary and spread over 301 rate centres.

Who holds these numbers

TELUS holds the largest share at 5 prefixes, 19.2% of the total, ahead of 12 other carriers. Code by code: in 403, TELUS leads with 3 of 11 prefixes ahead of 7 others; in 587, TELUS leads with 1 of 7 prefixes ahead of 6 others; in 825, Iristel Inc. leads with 2 of 7 prefixes ahead of 4 others; IXICA Communications Inc. is the only holder in 368. No carrier holds prefixes in every one of Canmore’s 4 area codes, while 6 appear in just one.

Wireless and wireline

6 of Canmore’s 26 prefixes (23.1%) are held by carriers whose registered name marks a wireless business: Rogers Communications Canada Inc. (Wireless), TELUS Mobility, Bell Mobility and Fido Solutions Inc. Wireline prefixes still outnumber them, carried by TELUS, Iristel Inc, Shaw Telecom Inc and Distributel. This is a sort by name, not a licence lookup, and a mobile prefix may have been ported to another network since.

How the allocation was built up

Canmore’s dated assignments run from 2000 to 2024. The busiest period was 2020–2024, when 6 prefixes went to 5 carriers. 2 prefixes (8%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 6 prefixes have been added, so the rate centre is still growing.

Canmore’s oldest prefixes, the ones the register leaves undated, belong to TELUS: this carrier made up the landscape before competition arrived. The first dated assignment went to Rogers Communications Canada Inc. (Wireless) in 2000. The most recent arrivals are ISP Telecom Inc. (2021), Fibernetics Corporation (2020) and IXICA Communications Inc. (2018), a sign that new carriers are still asking for numbers in Canmore.

Canmore has only 26 prefixes, or 260,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Canmore: the leader, TELUS, holds only 19.2% of the prefixes against 12 competitors, a sign of a highly fragmented market where cable companies, mobility brands and VoIP providers weigh as much as the incumbent.

Demand remains steady: 25.0% of the dated prefixes go back to the last ten years, the most active period being 2020–2024. The rate centre is growing at a regular rather than explosive pace.

Dialling a Canmore number

Canmore is served by 4 overlaid area codes (403, 587, 825 and 368). A 368 number is no more “out of town” than a 403 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Canmore shares area codes 403, 587, 825 and 368 with at least 20 other rate centres, including Calgary, Edmonton, Red Deer, Lethbridge, Medicine Hat, Fort McMurray, Banff and High River. The largest of them, Calgary, holds 756 prefixes in 368, 403, 587 and 825; the smallest on the list, Fox Creek, has just 14.

What a Canmore number tells you

A number attached to Canmore tells you that its prefix was issued to a carrier for this rate centre in Alberta, most often TELUS. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 13 carriers present here or to a VoIP service usable anywhere. Nor does it tell you who is calling: caller ID can be spoofed, and an Alberta area code is easy to borrow to look local.

Reading a register entry for Canmore: code 403-609 is recorded for TELUS, so every 403-609-XXXX number (10,000 possible) descends from that assignment. “Canmore, Alberta” there names a rate centre, not a municipality, and several area codes overlay it.
